To d/Zwhom zt 11mg concern.-

Be it known thatI, ERNEST K. MoCoY, a citizen of the United States,residing at Portsmouth,in the county of Norfolk and State of Virginia,have invented certain new and useful Improvements in Sanding-Tools g andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in rasplng and sanding tools, andmore particularly to a device of this character which may l portablepower-drill or similar too The object of the invention is to provide adevice or attachment of this character which will be simple inconstruction, durable and efficient in operation, and comparatively inexensive to manufacture.

. ith the above and other objects in view the invention consists ofcertain novel fea-' tures of construction, combination, and arrangementof arts, as 'will be hereinafter more fully described, andparticularlypointed out in the appendedclaims.

In the accompanym drawings, Figure 1 is I a longitudinal sectiona viewthrough my improved sanding-tool, showing the same a plied toa portablepneumatic or` power dri l. ig. 2 is an end elevation of the same. Fig. 3is a vertical transverse sectional view taken on the plane indicated bythe line a a of Fig. 1.- Fig. 4 is a detail view showing the manner inwhich the cylindrical body of the at- 'tachmentlmay be adjusted to clampthe sanding or rasping face thereon. Fig. 5 is a erspectiveyiew'of therasping-cylinder W 'ch may be substituted for the sanding-cylinder shownin Figs. 1, 2, and 3, ard Fig. 6 is a longitudinal sectional viewthrough aslightlymodified form of the invention.

My improved rasping and sandin tool 1 is in the form of an attachmentwhic may be secured upon a power-drill D of the usual form andconstruction or upon any other suitable portable tool having a rotatablespindle F. As shown in the drawin s, the tool D is'in the form of aneumatic dril of usual con-` struction, the bo y portion of which iscylindrical, as at C, and formed at one end with the usual removable capand a handle H, the rotary spindle F being at its opposite end andhaving a socketf to receive a drill or the hke.

The device or attachment 1 comprises a substantially cylindrical bodyportion 2, which is formed, preferably, of sheet metal and is dividedlongitudinally, as at 4, to Y erniit its edges to be adjusted toward andfrom each other to vary the diameter of the body. This adjustment ispreferably eected, as shown in Fig. 4, by providing projecting lugs 5adj acent to the edges 4 of the body 2 and by providing a set-screw6,which extends through a threaded opening in one of said lugs and hasits inner end enga ed with the other. lugs 5.are removab mounted inbrackets 7, which are secured adj acent to the edges ofthe body 2, sothat-when the screw 6 is turned in the roper direction the body 2 willbe eX- pan ed to clamp a sandin or ras ing surface upon its outer face.T e sensing-face is clearly shown in the first two figures of thedrawings and consists of a'cylinder 8 of felt or other suitablecushioning material, which is covered with sand cloth, pa er, or thelike 9. When lthe attachment is to e used for rasping urposes, acylinder 1() (shown infFig. 5 j is su stltuted for the sanding-cylinder.The cylinder 10 is of metal and has its outer face roughened, as shownat' 11, or in any other suitable manner, so that it may be used as arasp. It will be understood that the adjustment of the edges 4 of thebody2 is very slight, so that the working face of the tool 1s at alltimes cylindrical. The body2 is secured at suitable points by means ofscrews or the like 12 two removable heads 13 14. The latter are open orin the form of spiders, each The a stub-shaft 18, which has mounted uponit a handle 20, and on the inner face of said hub is an inwardl-pro'ecting shank 21, adapted to be secure v1n t e socket f of therotary drill-spindle F.

In Fig. 6 I show a modified construction in. which heads are' formedintegrally with the c linder. When this is done, the shank 21 is theonly point of connection of the attachment to the drill, the inner endofthe attachment being o en to ermit of ready access to an part of t edril D, as will be seen.

he construction, use, and, advantages of IOO the invention will bereadily understood from the foregoing description, taken in connectionwith the accompanying drawings. It will be seen that the device orattachment may bereadily applied to any styleof portable power-drill andthat it may be used in various ways. By grasping the handles and H therotating body portion of the attachment with its sanding or rasping facemay be readily moved over the surface to be operated upon.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without 'departing from the principle orsacrificing any of the advantages of the invention.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is-d 1. A rasping and sanding tool comprisinga longitudinally-slit cylinder, an abrasive cylinder on the slitcylinder, brackets 7 on the inner side of the slit cylinder, at the endsthereof and on opposite sides ofthe slit therein, lugs 5 in the saidbrackets. and projecting beyond the ends of the slit cylinder, andsetscrews connecting the Vsaid lugs, substantially as described.

2. A rasping and sanding tool for use in connection with a rotary powerhand-drill, and comprising a cylinder having a longitudinal split on oneside7 an abrasive cylinder on the split cylinder, means to diametricallyexpand and contract the split cylinder, and removable heads in saidsplit cylinder, one of said heads having a central opening to form thebearing for the cylindrical portion of the power-drill and the otherhaving a bearing for the shank of a handle for attachment to thedrill-spindle.

In testimony whereof 1 have hereunto set my hand in presence of twosubscribing witnesses.

ERNEST K. McCOY.
